SPECIFICATION forming part of Letters Patent No. 271,830, dated February 6, 1883.

Application filed July 18, 1882. (No model.)

Be it known that I, PATRICK GALLAGHER, of the city, county, and State of New York, have invented a new andimproved Machine for Scrubbing Floors, of which the following 'is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine by means ofwhich floorscan be scrubbed easily, rapidly, and conveniently.

Reference is to be had to the accompanying drawings, forming a part of-this specification, inwhich similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a'plan view of my improved floor-scrubbingmachine. Fig.2 is a cross-sectional elevation of the same on linear 00, Fig. 1.

The tank A, made of wood or metal, and of any desired or suitable shape, but preferably made semi-cylindrical, as shown,'is supported by rollers or casters a, attached to the lower edge of the circular frame B, on which this tank A rests, one-halfof this frame projecting from thestraight side of the tank. The faucets Q project from the straightside of the tank A into the projecting part of the frame B, asv shown. A vertical shaft,D, isjournaled on the tank A, in front of the straight side of the same, and on its upper. end is mounted a pulley, E, over which a belt, F, pa'sses,- which also passes over a pulley, G, the shaft of which is provided with a crank-handle, H, for rotatingthis pulley G, whereby the pulley E and the shaft D will be rotated. Two crossed arms, J, are attached to the lower end of the shaft D, and at the endsof these arms brushes K are held loosely,which brushes rest on the floor. These brushes are provided with upwardly-projecting pin tles or rods cl,.which pass through apertures in the arms J, thus permitting the brushes to move upped down slightly and adjust themselves automatically in these arms J A semicircular frame, L, surrounds the rear part of the circular frame B, and to its lower edge is attached a rubber strip, M, of

any desired thickness, the edge of which rests on the floor. The semicircular frameL is provided with 1ugsg,thr0ugh'which downwardlyouter surface of the frame B. By means of nutsj and washers 7c the lower edge of the rubber band M can be raised from the floor and can be pressedupon the same as desired.

The operation isas'follows: The tank A is filled with soapsuds or water mixed with any other cleaning-liquid used in cleaning floors. The brushes K are adjustable in the arms J, and the rubber strip or band M is pressed on the floor by means of the nuts 3' and washers 70. Then the operator opens the faucets G moreor less and rotates the armsJ carrying the brushes by turning the handle H, and moves the entire machine over the floor to be cleaned. The rotating brushes scrub the floor and clean the same thoroughly, and the rubber band M, resting on the floor, carries the water along with the machine, thus permitting this water to be wiped up by means of mops and likeimplements. erably provided with handles 1? for moving and guiding it over the floor.

This machine can be made of any desired size, as circumstances may require, and, ifdesired, the floor-drying apparatus, consisting of the frame L and the rubber band M, may be detached from the machine, and may be constructed as a separate part, which is passed over the floor behind the floor-scrubbing machine. However, I prefer to unite the two parts.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. A scrubber having each brush provided with separate pintles d, passing up through and remaining loose in the arms J of a rotary frame, as shown and described.

2. The combination, in a scrubbing machine, of the outer frame, L, with the inner frame, B, lugs g, hooks h, nuts j, and washers 70, whereby the frames are connected so as to.

admit of the adjustment ot' the rubber, as de-.
